The Miami Dolphins made a series of roster moves early Wednesday, signing receivers Julius Pruitt and Keenan Davis while waiving/injured Armon Binns and Jasper Collins.

Pruitt returns to the team where he spent parts of two seasons. Davis is a rookie out of Iowa, where he caught 112 passes for 1,470 yards and seven touchdowns in his four-year career. With the Hawkeyes, he played under offensive coordinator Ken O'Keefe, who is now the Dolphins' receivers coach.

Davis, who is 6-foot-3, 215 pounds, caught 111 passes for 1,459 yards and seven touchdowns in his Iowa career. He caught 47 passes for 571 yards and scored one touchdown as a senior. He signed with the Cleveland Browns after the draft, but got released last week.

He will be placed on IR once he clears waivers. Not sure of the ins & outs, but teams sometime waive a player before putting them on IR. That is how the Pats landed Ballard last year. The Giants waived him, not expecting him to be claimed. However, the Pats did.
